U.S. Judge looks into Giuliani's role in Iran sanctions case

NEW YORK (Reuters) - A U.S. judge on Wednesday ordered that he be given more detail about former New York City mayor Rudolph Giuliani and another lawyer's representation of a Turkish gold trader charged with conspiring to violate U.S. sanctions against Iran.

U.S. District Judge Richard Berman in Manhattan said he needed extra information to ensure that conflicts of interest did not prevent Giuliani and and former U.S. Attorney General Michael Mukasey from effectively representing Reza Zarrab, who is in U.S. custody.

Zarrab is accused of conspiring to conduct illegal transactions through U.S. banks on behalf of Iran's government.

Prosecutors said in a court filing last week that eight of the U.S. banks involved in the case were clients of Giuliani or Mukasey's law firms, and Giuliani's firm was a registered agent of Turkey, posing potential conflicts.

Benjamin Brafman, an attorney for Zarrab, said at a court hearing on Tuesday that Giuliani and Mukasey were working on a "diplomatic solution" to the case and would not represent Zarrab in court.

Giuliani, who has advised U.S. President Donald Trump, and Mukasey traveled to Turkey in late February to meet with Turkish President Recep Tayyip Erdogan about the case. Brafman said Tuesday that Mukasey discussed the trip in advance with U.S. Attorney General Jeff Sessions.

Zarrab, a dual national of Iran and Turkey, was previously arrested in 2013 in a Turkish corruption probe of people tied to Erdogan, then prime minister of Turkey.

Berman ordered Brafman to meet with Giuliani and Mukasey and submit information on what kind of work they were hired to do for Zarrab, what kind of work their firms had done for the banks and what the firms were doing to avoid conflicts.
